Q. A card is drawn from a pack of cards. The probability that the card will be a queen or a heart, is
A) $\frac{4}{3}$
B) $\frac{16}{3}$
C) $\frac{4}{13}$
D) $\frac{5}{3}$
Explanation
(c)
$P$ (getting a queen)$= \frac{4}{52} = \frac{1}{13}$
$P$ (getting a heart) $= \frac{13}{52} = \frac{1}{4}$
$P$ (getting a heart queen) $= \frac{1}{52}$
$P$ (queen or heart) $= \frac{4}{52} + \frac{13}{52} - \frac{1}{52} = \frac{4}{13}$
